Am from an IT services company for banking industry. Now we are going ahead to develop a chatbot for on-premise using Rasa Stack or Rasa Platfrom. Can anybody please give me the idea of the size of hardware for development, UAT and production? And what will be the database to be used for storing the session, chat history?

Ok, you can only install this http://rasa.com/docs/platform/dev/installation/ when you have the license which is of course then not free? I read this like that you can use this platform though but more detailed support or more services are then charged afterwards…
